The room itself was good, but it was not as nice as it looks in the pictures, and it was not as fully equipped as advertised.
As for the location, it's not so great. While it is possible to walk to Onnut station, it took us much longer than 10 minutes and it's not an easy walk, no proper sidewalk and a lot of traffic around.
The pool and gym was not as big and fresh as it looks in the pictures, and at the time of our stay there were restrictions to use it because of the current covid situation.
The host was not very responsive to messages when we had issues or questions.
We paid for 16 nights, but ended up only staying 5 nights in total.
